Mopar RB engines have been around since 1959, you think the dealers ever did this in the shop? Have you heard of a bearing failure epidemic?

They SAY they do.
It's what you want to hear right?
I'll go as far as to say I've NEVER worked in a disreputable place, and have worked in shops that work on very expensive machines....and the number of guys in the trade who do this is virtually non existant.
Do what you want to your car, but the simple fact that cars are out on the road, going 100's of thousands of miles without (or with ) doing this is proof it's a non issue

First time I changed the oil in my Cummins the filter had a lot of oil missing! Not anywhere close to the top of the filter  Wix too! I top off my Purolators on all my motors, slants included. Swish them around and it soaks into the media. I don't know if mine have the stand pipes in them. PL30001

I service, maintain and own 14 diesel engine trucks and they have huge filters on them and NO I don't pre fill any filters ever. I also change oil on 8 other passenger cars and trucks since 1981. I'm a oil change expert, can do one in minutes.  I've been to 3 Navistar factory engine schools and they warn you never to pre fill a filter because that oil or fuel won't be filtered upon fire up. I've been changing oil since 1976 and have run millions of miles with out ever a engine failure, I'd say your wasting your time pre filling and maybe run the risk of damage to your engine doing it, according to International trucks.

On a BB you'll be lucky to get it 1/4 filled. Take the filter and lay it on your bench and you'll see that the oil will drain right out of the outer row of holes.
Boy are you slow installing the filter. Sure you will spill some but if you are quick it will be minimal and most will still be in the filer after you get it spun on.
I have seen air locked filers that were not prefilled but never seen one air lock that was prefilled and this is on big block engines too. Have also heard chirping on some engines that for one reason or another took a little longer than others to fill. There is a definite difference in the rate that pressure build with and without filling. have witnessed it time and again. do what you please it is your engine and your oil and you $$$. I will continue to prefill always have and always will on my own and did on customer vehicles when I worked at the dealership and this was back in the day.

never fill mine ever on hemi or 440, spin on new filter, pull coil wire and turn key. all filled and primed, put back coil wire all done and fire 
I do the same thing, I try to wet the filter though. I dont have a 440 anymore but will soon. I fill the filter on the 273 3/4, still pull the coil and turn it over though.
Why in the world do so many people pull the coil wire and crank the engine???? Talk about engine damage, start the darn thing and get that oil pump working asap, plenty of oil left on the bearings. Mopar RB engins have been around since 1959, you think the dealers ever did this in the shop? Have you heard of a bearing failure epidemic?
Better question here is lets talk about when we change the oil, do it on a hot engine, let it drain, then refill it and start it within an hour. Thats how a repair shop does it. Don't wait overnight or longer to refill and start it. And no cold oil changes.
Add to this most reputable shops fill the filter before installing too.
As for spinning the engine before firing it is a recommended practice in the engine book to do this after changing the oil after winter lay up as a type of prelube but to do so with the spark plugs removed so that there is very little pressure exerted on the crankshaft bearings and the engine spins faster and freer.
When I do that I get a low pressure reading on my mechanical gauge. When I start it it already has oil pressure. If I dont the engine runs for a few seconds with no oil pressure, at a MUCH higher speed than the starter motor spins it at (especially if the choke is on).
Now I need to pin those needles, got to feel that heat

The '81 Mack R686ST I used to drive wouldn't start no matter how long you cranked it. Filled the filter and it was instant!
I guess before putting and engine together you need to filter the oil before installing the pistons? I usually dip them in 50-50 oil and STP.
I have built many engines and use 10w hydralic oil(aw32) on my sleeves and pistons. Heavy oil and stp is not helping the rings to seat and seal.

Sometimes I do and sometimes I don't.
I'll not worry about one way or the other.

I will raise the bar further...
Do you pre-oil that big dollar engine with an accusump before cold starting??
Accusump
And if he pre-oils it with Accusump, did he put new oil in the Accusump before cranking, thereby negating the purpose of the Accusump? Or did he NOT pre-oil the Accusump, thereby negating the purpose of changing the oil?!!!

An antidrain back valve prevents oil from reversing out the outer row of holes. You DO have to make sure there is only little oil visable past the threaded hole-which is easy tip the filter and it drains through the media into the case. You can even do this on a slant 6 (leave no 'visable oil' if you're quick

On high pressure diesel fuel systems, pre-filling the filter is a proven way to introduce dirt. Not recommended. Lube oil systems aren't as sensitive but the same concept applies. Pre-fill is an opportunity to get dirt in the wrong place.

This reply says it all,...no other replies needed. That was good! But YES,most definately fill your filter.
